Given numbers are 500, 504, 641, 390
The list of prime factors of all numbers are
Prime factors of 500 are 2 x 2 x 5 x 5 x 5
Prime factors of 504 are 2 x 2 x 2 x 3 x 3 x 7
Prime factors of 641 are 641
Prime factors of 390 are 2 x 3 x 5 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 500, 504, 641, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(500, 504) = 63000
GCD(500, 504) = ( 500 x 504 ) / 63000
= 500 / 504
= 500
Step2:
LCM(4, 641) = 2564
GCD(4, 641) = ( 4 x 641 ) / 2564
= 4 / 641
= 4
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 500, 504, 641, 390 is 1
